As Jiangxi Province stands out for its serious soil erosion in the hily red soil region of South China,research on its spatial and temporal changes was of true typicality.The combination of the remote sensing technique with the geographic information system technique showed significant advantages in the research.By using this technology,the change in soil erosion was studied in Xingguo and Yujiang of Jiangxi Province,with results indicating that soil erosion in the counties was gradually getting under control,both in area and in extent.The decreases in soil erosion area of the two counties were almost equal in percentage,with Xingguo County lagging slightly behind Yujiang County.However,soil erosion was still an outstanding problem in these counties.
